Leviticus 25:31

But houses in villages without walls around them are to be considered as open country. They can be redeemed, and they are to be returned in the Jubilee.

(New International Version)

'The houses of the villages, however, which have no surrounding wall shall be considered as open fields; they have redemption rights and revert in the jubilee.

(New American Standard Bible)

But the houses of the villages which have no wall round about them shall be counted as the fields of the country: they may be redeemed, and they shall go out in the jubile.

(King James Version)
